Non descriptive NullPointerException when accidentally inserting data of wrong type

[ifesdjeen]

When using an async execute function, if you accidentally pass argument of a wrong type, you will get an exception that's a bit hard to understand:

Caused by: java.lang.NullPointerException
        at qbits.alia$execute_async.invokeStatic(alia.clj:415)
        at qbits.alia$execute_async.invoke(alia.clj:380)

I'll debug / handle it later, just leaving info here not to forget..

Odd, seems that this path should be covered. Let me know what you find.

Closing, as this is now covered by the specs we provide (if you use them at dev time)
